WebMay 1, 2006 · We revisit the issue of finding proper boundary conditions for the field equations describing incompressible flow problems, for quantities like pressure or vorticity, which often do not have immediately obvious “physical” boundary conditions. Most of the issues are discussed for the example of a primitive-variables formulation of the … WebThe Navier-Stokes in full form for is not just a single PDE, but 4 PDEs + 1-2 algebraic relations (solve for 3 velocity components, pressure, density, and temperature). I think the millennium prize is for incompressible, so you don't need to deal with density and you might get to neglect temperature.
